Title:
SOFT MAGNETIC POWDER
Document Type and Number:
WIPO Patent Application WO/2023/153366
Kind Code:
A1
Abstract:
A soft magnetic powder according to the present invention has a glass transition temperature Tg, a first crystallization starting temperature Tx1 and a second crystallization starting temperature Tx2. The first crystallization starting temperature Tx1 is 400°C to 475°C. The difference between the first crystallization starting temperature Tx1 and the glass transition temperature Tg (∆Tx = Tx1 - Tg) is 50°C or less. The difference between the second crystallization starting temperature Tx2 and the first crystallization starting temperature Tx1 (∆T = Tx2 - Tx1) is 65°C to 135°C.
